Psychopathic Personality Inventory-Revised Developed by Lilenfeld and Widows he Psychopathic Personality Inventory was designed to provide psychologists with a timely test, which identified psychopathic personality traits (Leung, 2014). The traits assessed are not in relation to criminal or antisocial behaviors. The factors assessed are cold-heartedness, fearless dominance, and impulsive anti-sociality (Leung, 2014). The Psychopathic Personality Inventory-Revised is a shorter version of the original PPI. The following is a brief review of the PPI-R Test Purpose and Procedures The PPI-R is designed at a fourth-grade reading level, which allows the test to be administered in several settings such as forensic or clinical. The PPI-Revised was shortened and designed to reduce cultural idioms along with reading levels (Edens and McDermott, 2010).

The PPI-R remains a valuable tool used in both counseling and research (Leung, 2014). The findings of the 2013 article "Examining the Necessity for and Utility of the Psychopathic Personality Inventory-Revised (PPI-R) Validity Scales," by Anderson, Sellnorn, Wygant, and Edens, provided evidence for the utility, and need of the PPI-R.

    Dr. Theodore Millon created a system of personality assessment that consisted of eight domains of functioning. The domains are: behavioral domains (split into expressive acts and interpersonal conduct), phenomenological domains (split into cognitive styles, object representations, and self image), intrapsychic domains (split into regulatory mechanisms and morphologic organization), and biophysical domains which covers mood and temperament. Together, these domains come together to form a cohesive theory about how personality works, and how an individual will act on a day to day and situation to situation basis. This can be useful when assessing why people have done what they did, as in the case study provided to us today, the case of the adulterous County Sheriff.

    Introduction Serial killers have been terrorizing communities and populations since the 1900s. Serial killers are often seen as ordinary citizens, such as the first known serial killer H.H. Holmes, who was a graduate of University of Michigan’s medical program (“H.H. Holmes”). While other serial killers, such as Ed Gein Circa, displayed extreme antisocial behaviors (Frese).
